       Glad you like it ! Alas , I did not do a layout as such - more of a " tale that grew in the telling " kind of thing . Never really had the patience to learn how to do proper layouts !

Hello guys,

So lucky to find this post! Thx nick d for the schematic!

I am about to build it but I really want to control it with a CV pedal that works with 0-5V instead of a expression pedal.

How can I modify the expression pedal input to be able to use my CV pedal?

Thank you!

Cheers

          The CV from your pedal should go to the R connection on my schemo . You may have to make other changes , that would depend on which CV pedal you have .

Thank you for answer!

My CV pedal have Ground on the sleeve and + (0-5v) on the tip.

Do you mean I can just connect my tip to the 47k resistor that goes to circuit? And the sleeve goes to the 47k resistor that goes to ground?

Using a expression pedal, I suppose we will be sending something like 0-9v to the circuit. Using my CV Pedal that sends 0-5v, l suppose I wouldn't get the whole range of the parameter, right? (I am sorry, I don't have the skils to calculate this by myself. I can put the things together but I can't develop and change things).

I appreciate any help!

Cheers

Thank you, nick_d!

I can't find a 47k pot... It is ok to use one 50k instead?

Yep.
